Rm TOOL.

To all 'whom it may concern.'

`Be it known that I', WILLIAM C. SELBnEnE, a citizen of the United States, re-

siding at Billings,in the county of Yellow stone and State ofMontana, have invented certain new and useful Im rovements in Rim Tools; and I do hereby eclare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use'the same. Y .The present invention relates to a tire rim toch-and more particularly to a. tool adapted to contract and expand demountable rims of Vi5 the split type. v

An object ofthe present invention is to provide a colla sible and foldable tool `of this character w ich may be readily knocked down for convenientpacking'in a tool box o r other small space, and vwhich may be easily and quickly set up and applied to a rim without. any additional brace or suport.

further object is to provide a tire tool of this character which may be applied toa rim for contracting the same and for holding the same in contracted osition during the removal, repair and rep acement of the tire and tube, and which may then be separated to expand the rim without changing the osition of or removing the tool.

Tlie invention further provides a tire rim tool of this character which has a' pair of rim engaging members arranged to engage the rim at opposite sides of the 'split so as to prevent bending o'r warping of the rim out of place when the same is placed under tension in expanding and contracting the rim.

With the foregoing and other objects in View the invention will be more fully described hereinafter and will be particularly pointed out in the claim appended hereto.

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views',

v upper end of the a'ndle being broken away;

Fig. 6 is a similar view showin the hinged claws adjusted to op site si es of the split and showing the too in partly expanded position, the dotted lines showing the lateral Swingin of the tool for moving the ends of the spt rim past one another ready for contracting the rim;

Fig. 7 is a top 1an view of the tool applied to the rim or holding the same contracted; and

Fig. 8 is a similar view showing the 'tool expanded and in position immediately'subse uent to closing the rim..

eerring' to the drawing, the tool, comprises a lever or handle 10 of suitable length and having at oneend a handhold, and at'. its opposite end a series of o enings 11 tti* selectively receiving a pivot olt 12 when is adapted to pivotally support a pair of claws 13 and 14 arranged to swing in planes substantially parallel to the plane of the lever 10. The claws 13 and 14 are rovided with hinge knuckles 15 near their inner ends, the pintles of which are disposed at right angles to the pivot bolt 12 to permit the claws 13 and 14 to be swung toward and from each other. The claws 13^and 14; are,

therefore, free to pivot in different directie-ns j so 'as to provide, practically, a universal connection between the claws and the handle 10,

The handle 10 has upon itsinner end a stud 16 ,which rejects lateral] major axis of which extends lengthwisev of the handle 10 and is adapted to freely enter.

from one `side of the han le and is provi edelwith an elongated head 17 upon its outer.'e1 id,.thev

14.V The head 17 ofthe stud 16 is spaced fromv the side of the handle 1,0 a distance selected one of a number of openings 22v which are formed in the arm 19, the link being adapted to be swun upon the arm.

into various positions towar the handle 10 and being adapted to engage at its free turned end in one of the openings 11 of the handle. The free end of the link v20 has its laterally extending bill 23 undercut as'at 24 to provide a seat into which the marginal edge of the opening 11 is adapted to engage for locking the link 2() from 'slipping out of the opening. The inner end of the link 20 is of sutiicient len h to permit the link to be moved latera ly or engaging and disengaging the bill 23 withthe handle for holding the latter in retracted position.

The outer ends of .the claws 13 and 14 and of the anchoring arm 19,'are provided with rim engaging portions which. comprise spaced depending projections 25 and 26 with a rim edge receiving recess or cavity 27 between the projections. The projection 25 is relatively long and presents an outer flat surfaceadapted to engage across the inner surface of the rim while the projection 26 is relatively short and is tapered so asvto engage over the edge of the rim flan and between the same and the side wall o a tire casing. The projection 26, therefore, serves to direct the rim inwardly when contracting and the projection 25 serves to force the rim outwardly when it is being expanded.

In operation, the tool is first applied to a rim 28 as shown in Fig. 5 with the anchoring arm 19 arranged to one side of the Adiametric plane of the split 29 of the rim as indicated by the dotted line 30-30 in Fig. 6. The claws 13 and 14 are arranged at one side of the split 29 and at the side opposite to that occupied by the anchoring arm 19. The slight movement of the handle 10 now tends to break the split and-release the latch 31 or other fastening device which may be used to hold the ends of the rim together. When the ends of the rim 28 are thus separated they must be held in such positions by a suitable tool or merely by the Y abutting of the portions of the latch while out of registry while the claws 13 and 14 of the tool are properly adjusted for further manipulation.

After the latch 31 is released the claws 13 and 14 are spread apart so as to position one at each side ofthe split 29 of the rim, and the anchoring arm 19 is moved into the f said claws. inwardly wit medial plane of the split, as indicated by the dotted line 30-30 in Fig. 6, so that equal pressure may be placed upon the opposite ends of the rim to prevent distortion orundue ber ding thereof. The handle 10 is now swung to one side as shown by the dotted lines in Figure 6 so as to draw the claw 13, or the claw 14 as the case may be, inwardly to move one end of the rim 28 past the other,

dotted lines, the handle 10 may be swung backward uponthe anchoring arm 19 into the position shown in Figs. 3, 4 and 7, and vthe lever or handle 10 may be locked by the link 20 in such retracted position. When the parts are'thus retracted the ends of the f rim 28 are permitted to overlap as they are drawn inwardly so that the diameter of the rim 28 is reduced and the tire or the like may be easily removed and repositioned relative totherim. l l

It is apparent that this tool has a wide range of application to various sizes of rims, v

and that it maybe made out of various kinds of materials.

Assoonfas the tire is placed upon therim, the handle 10 may beagain swung forwardly so as to expand the tool and foro ethe claws 13 and 14 with their respective rim ends outwardly into the position shown in Fi 8. When the handle 10 is released the lati 31 is then brought to initial position and ma be locked and the to'olremoved.

t is understood that changes in orm,pro portion, size, and minor details may be made within the sco e of the claim without de parting from t e spirit or sacrificing any ofthe advanta es ofthe present invention.

What is c aimed is 1 A tire rim tool comprising a hn d lever, an anchoring arm pivoted atone ,end upon the lower portions 'of said hand lever and provided at its outer end with rim interlocking means for holding the anchoring arm from movement in either direction upon the rim, a pair of claws pivotally secured to the opposite sides of the hand lever and in spaced relation to the anchoring arm, said hand lever being' adapted to be swung back- A wardly upon the anchoringlarm for drawing respect to the anchoring arm and said claws having interlocking means upon their outer ends for engagement' with the rim to hold the "claws frommove/ment in opposite directions upon the rim, said claws having knuckles adjacent their pivoted ends adapted to hinge at right angles to the pivot. of the claws und said handle beinof adapted to be swung laterally and backwardly for contracting said claws and turning the same upon their pivots and upon said knuckles whereby the contxactiori. and .lateral swinging of the handle is adapted to move one end of ille rim past the opposite end thereof und to subsequently overlapsaid ends and contract the nm.
